G. R. BRINOKERHOFF, OF ROCHESTER, NEW YORK.

Specification forming part of Letters Patent No. 49,497, dated August 22, 1865.

To all whom it may concern:

useful Improvements in the Construction of Mowing-Machines which may be very readily converted into a reaper; and 1 do hereby declare the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making partof this specification, in which- Figure 1 is a top view of inyinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation, the driving-wheel D and the seat being removed. Fig. 4 is adetached view of the adjusted plate, shown by the dotted lines at P, Fig. 3.

Like letters indicate corresponding parts in the several figures.

This invention relates to that class of mowers having cast-iron frames; and it mainly consists in making the frame in such a way as not to require any drilling or fitting, except to rim out the two holes in which the journatshaft is inserted, and only requiring fifteen bolts to put the machine together andin running order.

To enable others to make and'use my invention, I will describe its construction and operation.

The bed-frame A is made, as shown in Figs. 1, 2, and 3, all the bolt-holes being cast in, and even the openings through the standards or hangers h and h to receive the axial arm or shaft S. The tongue T and the seat-bar B are removed in Fig. l and shown by dotted lines, so as to show the exact plan of the bed-frame A. The hangers h and h extend above the shaft, as seen in Figs.2 and 3. There are also two lugs, fand f", at the front end of the frame, and in case the machine is converted into a reaperthe reel-posts would be attached to these four points. The seat-bar B is pivoted to the standard f, and rests upon the shaft S astride of standard It. frame and makes room for the pitman-rod to work in. The knee-piece 7c is attached to the frame by the bolts 9. This knee has an arm, a, projecting from the front side, to which the carrier-wheel w is attached. The shoe G, to which the cutter-bar G is attached, is hinged to the base of the knee, the lip t, Fig. 3, of

The arch d strengthens the.

which projects sufficiently below to form astop for the shoe and cutter-bar to rest against and prevent their falling below a proper line. There is a guard-plate or shield to the frame A, and pivoted to toe or front end of the shoe, and, of course,in a line with the rear and middle hinge-joints, m and n. This bar-strengthens and supports the point of the shoe, and also prevents any cut grass or other obstructions from overriding the point of the shoe and getting back into the working parts to clog them. Several holes are provided in the arm a, whereby the carrier-wheel maybe raised or lowered, as may be necessary. There is ahole made in the rear end of the shoe at c to re ceive a bar, (shown by dotted lines j, Fig. 3,) whereby the driver can raise the cutters over any obstruction or raise them to a vertical position for transporting the machine to or from the field.

To change this machine into a reaper it is only necessary to remove the two bolts 9 and the axial bolt t. This detaches the knee from the machine A and the cutter-bar and shoe from the knee. The bar P, Fig. 4, is then fixed to the frame by the same boltsg, as shown by the dotted lines 1?, Fig. 3, and the shoe and cutter'har are secured to the bar 1? by the bolt 'r. This converts it into a rigid bar, and the carrier-wheel w is attached to the outer end of the cutter-bar. The bar P may be attached below the frame, as shown by the dotted lines, or above it, as circumstances may re quire. There isa stop (notshownin the drawings) to prevent the knife-bar from dropping out when the cutter-bar is raised.

What I claim as my invention, and desire to secure by Letters Patent, is-- e 1. The bed-frame A, constructed as shown t and described, having the hangers h and h for the support of the axial shaft S, and the lug f and f for the attachment of the reel-p when the machine is to be used asa reape 2. The detachable knee-piece 7c, hav projecting hanger-arm a for the carrie w, and the stop 1 all in the mannersh for the purposes described.
